Implant rehabilitation with new Advan Sinus Implant geometry

The purpose of this case report is to assess the clinical success of implant-prosthetic rehabilitation employing the new ADVAN GTB SINUS LIFT implant geometry in an edentulous, atrophic posterior maxillary site adjacent to the maxillary sinus. Three distinct ADVAN endosseous implants were placed in a partially edentulous patient with different residual crestal heights.

Introduction

Over the past decades, numerous principles in implant-prosthetics have undergone significant changes. Today, thanks to the advancement of implant micro- and macro-geometries designed to enhance primary stability and facilitate osseointegration, research predominantly focuses on the long-term success of rehabilitation, the preservation of crestal bone, and the maintenance of peri-implant soft tissues. Nonetheless, specific anatomical challenges persist in achieving primary stability and preserving marginal bone, such as immediate post-extraction cases and those with reduced residual crestal height. Implant-prosthetic rehabilitation of the maxillae offers an effective therapeutic option for edentulous patients. 

This approach proves superior both clinically and biologically when fixed prosthetic rehabilitation would necessitate sacrificing healthy dental tissue. However, this consideration applies only in cases of partial edentulism with mesial and distal teeth present; otherwise, removable prosthetic rehabilitation remains the sole clinical option.
